The browser that thinks like an IDE
Stop constant alt-tabbing between documentation, web apps and the terminal. LastBrowser integrates a real ConPTY Windows terminal, OpenAPI extractors and Model Context Protocol (MCP) right into the browser.
Real ConPTY Terminal
A full Windows pseudo-terminal in the sidebar. Run git, npm, cargo or docker right next to live localhost apps (Ctrl+`).
Terminal Doctor
Automatic error diagnostics for failed builds or stack traces. The built-in Doctor analyzes error messages and suggests fix commands.
Model Context Protocol (MCP)
Connect local and external MCP servers (PostgreSQL, filesystem, GitHub) with one click. Give AI direct access to your developer tools.
Full Offline Support via Ollama
Work offline on a plane or in high-security networks. Plug in local Ollama models (Llama 3, DeepSeek Coder, Qwen) with low latency.
OpenAPI & GraphQL Extractor
Sidekick automatically detects API documentation on websites and exports clean TypeScript types, curl commands or Postman collections.
Isolated Localhost Spaces
Test frontend and backend under different auth roles at the same time on localhost:3000 without clearing cookies manually.
Connect an MCP Server in 1 Click
Configure MCP servers in your mcp_servers.json directly under %APPDATA%\Lastbrowser:
{
"mcpServers": {
"postgres": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://localhost/mydb"]
},
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "C:\\Projekte"]
}
}
